COMMENTS: Do not use S3117 servos with gas or high power engine models, large
           gliders, or other models that require high torque
           Using supply voltage higher than 6V or applying high load to servo
            will shorten life
           Alway use the servo horn specially designed for this servo. Do not
            use conventional servo horns
           Excessive force or shock to the servo horn may damage the ultra mini
            precision gears inside the servo.
